Gerät für grössere Gasströme.

摘要

High gas flow requirements of large size lines are conveniently provided by a series of high pressure tubes connected to header means adapted to control the storage and distribution of gas to the lines at desired flow rates for relatively short periods of time. Gas thus supplied can conveniently be used as a propelling gas stream for the in-situ cleaning of large size lines under high exit velocity conditions requiring the supply of gas at a high flow rate not conveniently supplied by conventional pumpers.
